After rechecking the deposit details, Jerry realizes that the string length cannot be negative, so he decides to change the type of my_strlen function.

After rechecking the deposit details, Jerry realizes that the string length cannot be negative, so he decides to change the type of my_strlen function.

Jerry uses the git log command to observe the log details.

 [jerry @ CentOS project] $ git log 

The above command will produce the following result:

Implemented my_strlen function

Jerry uses the git show command to check the deposit details. Git specifies the command to be taken from the SHA-1 deposit ID as a parameter.

 [jerry @ CentOS project] $ git show cbe1249b140dad24b2c35b15cc7e26a6f02d2277 

The above command will produce the following result:

He changes the type of function from int to size_t. After checking the code, he reviews the changes by running git diff.

 [jerry @ CentOS project] $ git diff

Git diff indicates the '+' symbol before the lines that add new and adds '-' to the deleted lines.
